Fourier Series Visualizer

Fourier Series Exapansion

This applet allows you to visualize the convergence of the Fourier series expansion of a given function

on the interval

. You can choose your own function

and interval

. Click the checkboxes to toggle the visibility of the graph of

, the partial sum of the Fourier expansion, and the separate component waves. Change the slider to adjust the number of terms in the partial sum.
